JOHN MEEHAN, OF NEWARK, NEW JERSEY. Letters Patent No. 67,563, dated August 6, 1867.

IMPROVEMENT IN TANNING.

1, JOHN MEEHAN, of Newark, county of Essex, State of New Jersey, have discovered a process by which hemlock leather, after having been thoroughly tanned 'in hemlock barks or liquors, may be changed by my process to possess nearly all the qualities of leather tanned in liquors three-quarters oak and one-quarter hemlock.

I will first describe what I consider the best means of carrying out my invention, and will afterwards designote the points which I believe to be new. 7 To one part muriate of tin add two hundred and sixty parts of strong oak liquor, extracted about its follows: what tanners generally call a. double liquor, that is, the extract of one leach pumped on to fresh bark and boiled about four hours, then allowed to cool down to a temperature of'from 100 to 110, the leather to be handled in that liquor for two and a. half hours. If the desired efiect be not. produced in that length of time a very small proportion of the acid may be added, and the leather remain longer in, according to the judgment of the person using it.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The within-described process of changing hemlock leather so as to obtain in good part the qualities and appearance of oak-tanned leather, substantially asherein specified.

In testimony whereof I have hereunto set my hand in the presence of the subscribing witnesses.

JOHN MEEHAN,
